“…Superficial venous incompetence is almost universal and is the predominant cause of venous hypertension in approximately half of limbs with venous ulcers, particularly in younger patients with good mobility 9. Venous function in patients with mixed deep and superficial disease should be investigated by ambulatory venous pressure measurements 10. This involves cannulation of a foot vein and the use of tourniquets to occlude incompetent superficial veins to select those patients who may benefit from superficial venous surgery.…”

“…14 In a study of 360 limbs, the mean ambulatory venous pressure for limbs with reflux in the superficial venous system only was 61 mmHg. 15 In this case, a rapidly disseminating lichen sclerosus manifested itself overlying a mildly varicosed long saphenous vein. It is proposed that venous pressure in this range acted as the stimulus for the Köebner response in the context of a rapidly generalizing lichen sclerosus.…”

A 52-year-old woman presented with an 18-month history of genital and extragenital lichen sclerosus. In addition to the classical genital findings, lesions of lichen sclerosus were present over her back, chest and the medial aspect of her right thigh and leg. On her right thigh and extending to her right leg, lesions of lichen sclerosus displaying the Köbner response were noted over the course of a varicosed long saphenous vein. There were no features of varicose dermatitis in the region displaying the Köbner response. It is proposed that the ambulatory venous pressure within the vein acted as a stimulus for the Köbner response.

“…In the longitudinal section the mean blood flow velocity in the vessels was determined. Both VFV and VFA were calculated by the mean blood flow velocity ( v m ) and the diameter ( d ϭ 2 r ) of the vessels with the formula VF ϭ v m ϫ r. 2 Division of VFV and VFA calculates the VAFI (Figures 1 and 2). VAFI measurement was performed at a constant ambient temperature.…”

“…Numerous data on venous hemodynamics can be obtained using plethysmographic methods or ambulatory venous pressure measurement, which is accepted as a standard test of venous insufficiency. [2][3][4][5][6] But the extent and restricted repeatability are limiting factors. Photoplethysmography, strain gauge, or air plethysmography only allow an approximate calculation of the competence of the venous system 7-9 because of widely dispersed standard and pathologic values.…”

background. Volume flow, as the product of the mean blood flow velocity by the cross sectional area, means an interesting hemodynamic pattern that can be calculated by duplex. objective. To quantify the severity of venous insufficiency using the correlation between the volume flow in the common femoral vein (VFV) and artery (VFA), called the venous arterial flow index (VAFI). methods. A total of 163 consecutive patients were included: 46 patients with postthrombotic syndrome (PTS, group 1), 38 patients with complete varicosity of the greater saphenous vein (group 2), 40 patients with only segmental or truncal varicosity (group 3), and 39 patients with competent veins (group 4). Under standardized conditions, duplex sonography was performed to calculate volume flow in the common femoral vein and ar-tery as a product of mean blood flow velocity ( v m ) and precise diameter ( d ϭ 2 r ) of the vessel due to the formula VF ϭ v m ϫ r 2 (L/min). Division of the venous and arterial volume flow data calculated the VAFI. results. Significant differentiation of VFV ( P Ͻ .001) and VAFI ( P Ͻ .0001) between varicose veins and healthy limbs were found. In PTS the mean VFV was 0.50 L/min and the mean VAFI was 1.465. In the complete varicosity group, mean VFV was 0.46 L/min and mean VAFI was 1.48. In group 3, the mean VFV was 0.41 L/min and the mean VAFI was 1.31. In healthy persons, mean VFV was 0.36 L/min and mean VAFI was 0.87. conclusion. The VAFI can be used to quantify the hemodynamic severity in venous insufficiency.
